THERMAL MANAGEMENT COMPOSITE MATERIALS

Abstract
Graphite aluminum composites for use in thermal management applications, such as heat sinks, are manufactured using pressure molds. The materials may be mixed previous to insertion into the mold, or can be mixed within the mold. Further, graphitic particles, such as graphitic needle coke surfaces, can be coated with the aluminum before the mold process is performed. Further, ceramic sheets can be inserted into the mixture before the mold process is performed so that the molded material can then be sliced to provide a carbon aluminum composite plate with a ceramic sheet on one of its surfaces.

Claims

1. A method for making a carbon-aluminum composite comprising pressing a mixture of graphitic particles and aluminum in a heated pressure mold.

2. The method as recited in claim 1, further comprising preparing the mixture of graphitic particles and aluminum by mixing the graphitic particles with aluminum particles.

3. The method as recited in claim 2, wherein the graphitic particles comprise carbon nanotubes.

4. The method as recited in claim 2, wherein the graphitic particles comprise graphitic needle cokes.
